IMPROVEMENT IN MACHINES FOR MAKING BOBBINS.

Specification forming part of Letters Patent No. 172,622, dated January 25, 1876,' application filed June 17, 1875.

To allwhom t may concern:

Be it known that we, GEORGE W. GLAZIER, of Salem, and OSCAR E. WAIT, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in a Machine for Making Bol bins, of which the following isaspecification:

Our invention consists of the peculiar construction and combination of devices, all as hereinafter described.

In the accompanying drawings, Figurelis a perspective View of a machinefor making bobbins which embodies our invention. Fig. 2 is a vertical section of a detached portion. Fig. 3 is a front' elevation of said machine. Fig. 4 is a vertical section of the same oufline m of Fig. 3, and Fig. 5 is a top view of a detached portion of the same.

The machine is designed for taking square blocks ofthe proper length for a bobbin, and automatically boring, reaming, turning, and slotting, thereby producing nished bobbins more uniform in size, and at much less expense, than by the methods heretofore employed.

Motion is imparted to the driving-pulleys of the various shafts, spindles, 85e., by means of suitable belts. (Not shown.) Blocks7 the crosssection of which is va square fully equal in its dimension to the proposed diameter of the largest portion of the bobbin designed to be produced, are placed or stacked in the hopper A lengthwise with the machine, as shown in Fig. 3.

The main shaftB is driven in the direction indicated by the arrow in Fig. 3, and the cam a on the left-hand end of said shaft engages with a forked lever, b, the upper end of which lever rests in the hub of a spider, c, to throw said spider toward the center of-the machine. Two arms of said spider c are connected with drill-spindles ddand one arm with the plungerrod c. Therefore the movement of the spider necessarily carries with it the spindles d d and plunger-rod e, the latter of which willv strike against the lower one of the blocks in the hopper and push it forward into the box C. The cam a then draws the lever b and the parts connected therewith back to their former position, when all the blocks in the hopperA fall just the thickness of the block last removed.

Another revolution of the shaft B, and the auger, D, Fig. 2, driven by a belt, (not shown,)

and as the block protrudes from the box it enters the auger, and is turned oi to a size designed for the head of the bobbin, the interior of the box C'being of such size as to prevent the block from rotating therein; but as the chisel in the end of the hollow auger is set beveling to make a better' cut, there is a portion of the block at the rear end not turned when it leaves the box C. Therefore some device must be employed to prevent the block from rotating with the hollow auger.

Upon the shaftB there is acam,f, Fig. 3, above which there is a slide, g, working through the frame of the machine, and in the upper end .of the slide g there is a roller, k. Just as the block is about to leave the box C the cam f engages with the slide g, and throws its rollerV upward, andV embeds the edge of said roller in the turned end of the bobbin-blauknow pro# truding through the hollow auger, and prevents said bobhin-blank from rotating' therein while being grooved by the chisel of the hollow auger, after which the vcani allows the slide and roller to withdraw. The indentation in the wood made by this roller is upon that portion which will in the nished bobbin be the smallest, so that the necessary subsequent turning wholly removes the mark made by thei li oldin g-roller.

Another revolution of the shaft B, and al1-f other block is pushed from the hopper, carry-` ing before it the two preceding blocks, when the rst one enters a socket in the lower part of the revolving head E, While the second block is turned off in the hollow auger, as before described.

The head E has six sockets, and revolvesy around a stationarycam, l. Clamping-rodsz' extend from the cam lto the sockets, which rods are provided with springs to witlhdrawthe rods from the sockets, the cam being smallest upon its under side, so that when each socket comes directly underneath the short arm atthe under side of the cam the spring wholly withdraws the end of the rod from the socket. A ratchet and pawl, j', Fig. 3, operated through means of a lever and cam, K, .causes the head E to r.volve with an intermittent motion, stopping at each sixth part of a revolution. A spring (not shown) engages with slots in the periphery ofthe head E, to prevent it from rotating when/thev blanks in the sockets are being operated upon, which spring is disengaged from the head by an arm extending to the rear of the ratchet and pawl j; but this mechanism for holding the head we do not claim as new, and any otherknown mechanism may be substituted therefor without changing the nature of our invention.

At the first movement of the head E after receivingthe bobbin-blank, as before described, the en'do-fclamping-rod is thrown into the socket by means ofthe cam Z, so as to lirinly bea'r against the blank'and prevent it from turning within the socket.

'J ust in front of and under the head E there is an evener, F, which consists of two spring-arms, standing obliquely to the head, andA being the farthest apart at the rear, also so far under the head that the socket willy passy it before the clamping-rod gripes the blank within the socket. In case a blocky is thrown too far through the socket, or that they vary in length, the spring-arms of the evener F will' bear against the ends of the blanks and` move them lengthwise therein, so as to bring them central with the evener, and if the evener is set centrally with the head it will bring the blocks with each' end protruding the saine distance upon both sides.

Another revolution of the shaft B, and anotherr round bobbin-blank is forced into the lower socket by pushing a block from the hopper, as before described,-and simultaneously therewith the spider c is brought forward, and with it theI spindles d d, the front one of which carries a drill and chisel, which drills a hole partially through the center of the blank and squares the end designed for the head.

'Another revolution of the shaft B and the head makes another one-sixth of a revolution, and the cam G, through means of rod m, causes the saw H, driven by abelt, (not shown,) to pass by the end of the blank and cnt a slot across itshead. Atthenext revolution of the shaft B and movement of the head E the drill in/"the rear spindle d, and one in spindle d at the right ofthe head, both move toward the head. and drill a central hole in each end of the blank, which holes nearly meet each other.

The next movement of the head, and the sa-me blank is brought in front of the spindle d, when thehole is drilled completely through, and then in front of spindle df, when the central holev is reamed out, these spindles d d d" being moved forward by means of a spider, c',

, lathe-spindle.

A cam, P, through means of levers q r and lever b', and cam a', as before describedfor the spindles upon the opposite end of the machine.

If the machine has been properly supplied with blocks all parts of the machine work simultaneously-that is, so soon as the block moves from one device to another, it is fol#- Aout by it and thrown upon one of the spindles u of the horizontal revolving head I. In the center of this head there is a recess'or cup, from which cup holes lead through the spindles n n n n, as indicated by broken lines in Fig. 5, and at the shoulder o of said spindles there is a branch orifice opening into the main passages, in vall of which wicking is supplied.

The cup in center of head I is supplied with oil, which is carried bythe wicking to the shoulders o and ends of spindles n, so as to keep them welllubricated. Acam, J, on shaft B imparts a reciprocating motion to a segmental gear,sK/, Fig. 3, which meshes into a gear, L, loosely fitted upon the lower end of the vertical shaft of the head I, which gear L carries a pawl, (not shown,) that engages with a ratchet having four teeth on the lower end ofthe shaft of the head I, whereby at each revolution of the shaft B the head I is rotated one-fourth of a revolution.

Immediately underneath the head I, at'tlieA lower end of' its shaft, there is a cam, M, Fig. 3, which engages therewith, and raises the head I a short distance just previous to every partial revolution of it, whereby the spindles andthe work on them are lifted out of the way of the turning and other tools to pass by them without contact therewith.

The shouldersoof the spindles n on head I serve the purpose of a tail-block for the lathes hereafter described. vIf desired, a collar may be placed upon the spindle at this shoulder.

The round and bored bobbin-blank, .after being forced yfrom the head E onto theispindle n, is brought to thefront and stopped directly in front of the lathe-head N, when the cam O, Fig. 3, operates the angle-lever p to throw the spindle of the lathe-head N forward, and force its dog into the slot at theend of the bobbinblank, so as to cause spring s, moves the tool-carriages Q R back and forth. The tool-carriage Q ofthe lathe N is 'supported at the front by a round way, t, upon which it can turnso asto allow of its rear endbeing raised'and lowered. At the' it to revolve with the` rear of the lathe N the tool-carriage is supported upon an adjustable way, u, which way is secured to a hinged lever, o, which rests upon the cam S, having two concentric faces,

p as shown in Fig. 4..

Just at the time that thelathe-spindle engages lwith the bobbin-blank to revolve it, the lever o rests u'pon the largest one of theconcentric faces of the cam S, and the cutting-tool is at the tailof the lathe-head T, when the cam U and lever uf throw the spindle of the lathe T forward to engage with the bobbin and revolve it. The carriage R and its cutting-tool then pass under the bobbin to smooth it, and then return. The head I then makes another quarter-revolution, and stops with the bobbin at the rear of the machine, and at the next movement of the carriage It the catch V engages with the bobbin and crowds it oli' from the spindle, so that when it again'comes in front ot' the socket in the head E it is ready to receive another blank, and so on with each successive spindle of the head I, and carrying them on to the various parts and through the various operations before described.

Although our machine is designed for making bobbins, it is evident that by changing some of the drills, chisels, cams, and other minor details, it may be used for making various hollow articles, such as spools, pill-boxes, &c. By changing the shape of the cam S, or substituting therefor camsof other shape for raising and lowering the adjustable Way u, the shape of the work turned upon the lathe N can be varied, as may be desired.
